Lab Assignment Sheet Exploring Impulse-Momentum of Car Crashes (Week 11) Model or Topic Explored: In this lab, we will crash the IOLab unit into a solid object like a wall or sturdy book. We will introduce the concept of momentum and look at how it changes during a crash. We will make use of the Force and Wheel sensors to collect data to see how force, time, and momentum are related. Name: Tori Salorenzo Date: 2/27/17 Observables: The cart bounces back, there is a change in the cart’s velocity, the cart imparts force on the book, and the book imparts force on the cart Measureables: Velocity (m/s) of the cart, the mass (kg) of the cart, force (N) using the force sensor, and the time (s) of impact Constants: the mass (kg) of the cart Problem Statement: How are momentum, force, and time related? Prediction: Momentum has a linear relationship with both force and time. This is because, ∆p = F net ∆t. Experiment: Procedure, Tools, Diagram of Apparatus: I chose these three books to withstand a collision with the IOLab cart. In each trial, a
